Abstract
A fatty acid feed stock for dimerization and a method for preparing a fatty acid feed stock from a first source of fatty acids which are rich in oleic acids and from a second source of fatty acids which are rich in linoleic acids. In particular, the present invention is directed to blending from about 35 to about 45 percent by weight of crude red oil with from about 55 to about 65 percent by weight of soap stock derived from soy bean oil to provide a fatty acid feed stock.
Claims6
A fatty acid feed stock suitable for use in the preparation of dimer fatty acids having properties generally similar to dimer fatty acids produced from tall oil fatty acids, said feed stock comprising a distillation product derived from about 35 percent to about 45 percent by weight of crude red oil and from about 55 percent to about 65 percent by weight crude soya fatty acid soap stock, said feed stock having a composition of from about 0.5 to about 2 percent by weight of palmitoleic acid, from about 40 to about 52 percent by weight of oleic acid, from about 20 to about 40 percent by weight of linoleic acid, from about 2 to about 7 percent by weight of linolenic acid and from about 3.5 to about 11.5 percent by weight of saturated fatty acids.
